【摘要】：为了研究人在跑步过程中速度对膝关节运动生物力学的影响规律,基于Kane方法和半物理仿真方法建立下肢动力学模型,以健康男性青年为对象,对不同速度下的跑步过程进行实验研究和数据分析,建立以速度为自变量的膝关节运动模型.研究结果表明:步态初期足跟落地时刻,跑步速度越快,小腿向前伸展程度越大,越接近与大腿共线;步态中期,大腿向后伸展,小腿与大腿接近共线的最大程度,此时膝关节背面的韧带拉伸量最大,并且速度越慢,共线程度越明显;膝关节最大屈曲过程出现在步态后期,并且最大角度随着速度的增加而增加;随着跑步速度的增加,膝关节曲线前移.实验结论可用于康复机器人、类人机器人等研究领域.
[Abstract]:In order to study the effect of human speed on the biomechanics of knee joint movement during running, a lower limb dynamic model was established based on Kane method and semi-physical simulation method. The experimental study and data analysis of the running process at different speeds were carried out, and the knee joint motion model with speed as independent variable was established. The results showed that the faster the running speed, the greater the forward extension of the calf and the closer it was to the thigh at the beginning of the gait, while in the middle of the gait, the thigh stretched backward, and the calf and thigh were close to the collinear degree. At this time, the ligament on the back of the knee joint has the largest amount of stretching, and the slower the speed, the more obvious the collinear degree; the maximum flexion process of the knee appears in the late gait, and the maximum angle increases with the increase of the speed; with the increase of the running speed, The curve of the knee joint moves forward. The experimental results can be used in rehabilitation robot, humanoid robot and other research fields.
